Improvement in machinery for printing yarn

Letters Patent No. 83,103, dated October 13, 1868.

IMPROVEMENT IN MACHINERY FOR PRINTING YARN.

The Schedule referred to in these Letters Patent and making part of thename.

To all whom tt ma/y concer-n:

Be it known that I, EDWARD J. STEPHENS, of Pawtucket, in the countyofIrovidence, and Stat-e ot Rhode Island, have invented a new and usefulImprovement in Machines for Printing Yarn; and I do hereby dcclare thatthe following specification, taken in connection with the drawingsmaking a part ofthe sume, is a full, clear, and exact descriptionthereof.

l The drawings represent the machine, the purpose ol' which is to printyarn in differentcolors, partly in sidel view, and partly in section.

A A fire two cylinders, which, it is to he iunlerstood, nre mounted onaxles, B B. IThe surfaces of such cylinders are furnished with ribs, a,upon whose faces thc coloring-matter for the print is to be spread, byappropriate distributing-color rollers, in a well-understood way.

O represents thel yarn passing between the cylinders A A in a linetnngential to their surfaces, and receivimc,r n. print upon both sides,from the ribs of the cylinders respectively, als it passes along.

l) l) are distributing-color rollers, of which any convenient number muybc employed, and are arranged to wallow in :L mass of(mloring-mattcrpla'ced ir. troughs, E E, as is usual.

The invention resides in the in cuns employed for causing the severaldistributing-nllcrs so furnishing coloring-mattei' to skip, during therevolution of the pri-nt-ing-cyliinler to which they belong, all thoseribs which :tre to bc furnished with some other color than that whichthey themselves supply.

Upon thc ends of the` axles of thc cylinders A A arc placed the toothedwheels l* lf, which give motion to the series of distrilnlting-cohn'rollers D l), pertaining to euch cylinder rcslwctively, such rollershnvinbr pinions, G, keyed to their n-xlcs.

lhe rollers l) lnwc their axles, H, set in journal boxes, b, which nrcsupported upon springs, c, thus constituting for cnch roller n),'icldinp` bearing.

It will hc observed that. thc teeth ofthe scvcrnl pinions G are not allcut of uniform dcptl1',lbr cach wheel, and that, in consequence, theends of the teeth of the driving-gears F will bottom in some of thespaces between the teeth of the pinions with which they engage. Fromthis, it is apparent (the bearings of such pinions being yielding) thatthe distance between thc surfaces ofthe color-rollers D and the faces ofthe ribs a, upon the cylinders to which such rollers belong, will bevariable, land will be' determined by the variations in the depth of theteeth of the pinions.

In the operation of the machine, which is driven by a belt in anyconvenient way, the several color-rollers will obviously supply color tothe faces of such of the ribs only of the cylinders which they serve asthey are permitted to come into contnct with, and that they will skipthe surface of every rib where, by reason of the shallow depth to whichthe teeth of thc pinion are cut at that point in its revolution, theends of the teeth of the gear-wheel l cause such rollers to be forcedaway.

By arranging the two priming-cylinders A A, and the distributing-rollersD, so that correspomling ribs shall receive the sinne colors, all thegoed results can be accomplished which can be produced by any othermachine of the class to which it belongs. It is apparent, too, that allvarieties of patterns which can be produced b`y different combinationsof colors can be printed upon this machine by simply varying,lthemrrangement of the pinions; und, for convenience in readily adjustingthc machine to different patterns, it will be found advisable, insteadof having n number of ditl'crent pinions, to employ one set ot' pinions,with teeth cnt o1' uniform depth, and inscrt'small strips of \vood orother nnttcrizil, to lill up partially the spaces between such of thetccth as the printingl of the pnttern selected requires.

Whnt l clnini as my invention, and desire to secure by Letters lntent,is

ln combinnlion with suitable ribbed printing-cylinders, A A, a seriesot' furnishing-color rollers, D D, hung in yielding lnnrings, landoperated by menus of pinions (l, with tccth ol variable depth, or thoIequivalents ihox'col', in the nnumcr suhstantinlly as described. for thcpl'uposcs spcciiicd.h 1
